A rolling bearing comprising outer and inner rings 1, 3 having outer and inner ring raceways 4, 2 respectively, rolling elements 5, 19 which are disposed so as to rotate between the aforementioned raceways, an cage 6 for distributing the rolling elements evenly in their rotational direction between the raceways having cage pockets 8, 21 with openings 23 between 80-93 % (A) of the diameter C of the rolling element 5, 19 and wherein the rolling bearing arrangement is used with a fluoro-containing polymer lubricant 14 or in an atmosphere comprising a gas containing fluoride. The specific arrangement also comprises a weld line 26, a clamping area D and clamping fingers 24. The arrangement aims to reduce the wear on components, such as vacuum pumps, which operate in severe conditions and also improves the lubrication performance. |
